LAMA1 and esophageal squamous cell carcinoma: For example, circSPARC upregulates JAK2 expression by sponging miR-485-3p, leading to accumulation of phosphorylated p-STAT, which in turn promotes CRC cell proliferation and metastasis [37]; in addition, circPDE3B can induce EMT to regulate ESCC cell proliferation, migration, and invasion through the miR-4766-5p/LAMA1 axis [38].
